The afternoon light streamed into David's kitchen, painting stripes across the linoleum floor. He leaned against the counter, absently stirring his lukewarm coffee. His limbs felt leaden, and his thoughts wandered aimlessly.

A shadow fell across the doorway. It was Mr. Peterson, his neighbour, a small glint of metal on his front tooth.

"David! Mind if I run this past you?" Mr. Peterson held up a drawing, apparently for a fence design.

David gave a long, slow blink. The sketches seemed to blur before his eyes. All he could think about was finding a dark place to rest.

"Looks...fine," he managed, his voice a low monotone. He wanted to escape, to disappear into the quiet.

Role in Research

This story is one of 1,000 stories generated for the emotion sleepy. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 sleepy stories, after denoising with neutral dialogue baselines, produces the sleepy emotion vector -- a direction in the model's 5,376-dimensional representation space.
